There isn't all too much on the expiries board for the day ahead, with the full list seen below.The only notable one perhaps is for EUR/USD at the 1.1415 level. Even then, the expiries don't tie to any technical significance so I would not attach too much impact from it on price action. The dollar remains in a push and pull mood as markets continue to digest US-Iran developments as well as the continued selloff in tech shares.Coming up later today, there will be the Fed meeting to add to the mix. As such, expect broader markets to hold a more pensive mood until we get to that.That being said, risk sentiment remains on edge and is staying on the defensive after another bloodbath in Asia today. Stocks are under pressure, tech shares especially, and that could lend itself to a broader reaction in other markets too. But for now at least, it seems more isolated for the most part.Still, one cannot be too cautious when dealing with the kind of market mood we are seeing. That especially with US-Iran tensions still having the potential to go off the rails at any point in time and watchful eyes on whether the Fed will take a more hawkish step later today. I still think the latter is very unlikely but again, there's no such thing as being overly cautious when dealing with the mayhem we're seeing.But circling back to the expiries board, there will be bigger fish to fry tomorrow alongside potential month-end shenanigans. For today, don't expect much in terms of influence and impact from the list above.For more information on how to use this data, you may refer to this post here.
